I bought quite a bit of stuff from them, and had no problems with getting the order. The JBA headers I ordered came without the gaskets, not that I would have used them anyway, but when I called they jumped right on it with JBA and got a set sent overnight. The only negative thing I can say is getting a hold of George can be tough if you need any tech help, but he will get back to you either phone or e-mail. I found thier pricing to be good, and thier sales people honest and friendly, so I'll be going back.
Just keep in mind, some products are drop shipped directly from the manufacturer, and they only help push it along so it could cause a delay once in a while.
